Notes: uses 8 pc. 4Mx1 Chips (541000-80); made by Newell, later by
FTE; seems to be very incompatible to existing software and
bankswitching cartridges (OSS, Atari, etc.), because normal RAM at
4000-7FFF is NOT available - only extra Ram/Ramdisk banks. With one
PIA chip there is simply no bit left to switch between main RAM and
extra RAM / Ramdisk. But with the installation of a second PIA chip
one would be able to do so. Furthermore one may use (almost) any
setup or banks he likes then (with a second PIA chip one could
control up to 256 Megabytes of RAM). Basic: To be able to select the
internal Basic, connect a toggle switch between ground and the
motherboard where PB1 was removed (PIA `Hole' 11). The switch is not
much different than the Option Key, and I found it more versatile.
(Wes Newell); OS: It is possible to maintain OS bankink using 4 Megs.
It requires moving the OS into RAM before any banking of that Bit
occurs. Use MOVEOS File on the [Newell-Software-] Disk. (Wes Newell)
Atari Basic: no! XL/XE Selftest: no (?) Antic access: no!
